Modifying Directory Permissions

Directories, marked by d, also have three types of file permissions: read, write, execute ; but they signal different behavior from file permissions. This permissions can be changed using the chown command.

user@host:~/directory$ ls -l
total 24
dr-xr-xr-x 2 user users 4096 Apr 4 12:42 list_files_on_dir
d-wx-wx-wx 2 user users 4096 Apr 4 12:21 modify_dir_content
d--------- 2 user users 4096 Apr 4 12:24 secret_directory

• r or list means that the content of the directory can be listed (files an subdirectories).
• w or modify means that elements may be added or deleted from the directory.
• x or access means that the directory can be entered (usually with cd).
